摘要： An image forming apparatus that prevents transfer defects such as the occurrence of white spots includes a photoreceptor drum, a transfer roller, a transfer bias application circuit that applies a transfer bias to the transfer roller, a static elimination needle that eliminates static of a recording paper, a static elimination bias application circuit that applies a static elimination bias to the static elimination needle, and a printer controller. The printer controller controls the static elimination bias application circuit so that a potential difference between the static elimination needle and the recording paper during the period from when a front end region of the recording paper passes by the static elimination needle until when a front end of the recording paper comes into contact with a conveyance guide becomes smaller than the potential difference during the period that the front end region of the recording paper passes by the static elimination needle.

摘要： A charging method for charging a photosensitive material of, for example, the photosensitive drum of an electrophotographic copying apparatus is accomplished by bringing an endless electrically conducting flexible sheet containing a brush roller into physical contact with the surface of the photosensitive material and applying a voltage to the electrically conducting flexible sheet. The electrically conducting flexible sheet is a laminate of a first resistance layer positioned on the side of the brush roller and a second resistance layer positioned on the outer surface of the first resistance layer. The second resistance layer has an electric resistance greater than that of the first resistance layer. The method using the laminated flexible sheet makes it possible to uniformly and stably charge the surface of the photosensitive material without the life of the photosensitive material being deteriorated and without permitting the output of the power source to drop even when defects, such as pinholes, exist in the surface of the photosensitive material.

摘要： In an image forming device, toner in a developing unit is efficiently utilized. A printing unit includes a developing unit, a toner cartridge, a photo-electronic sensor, a CPU and a counter. The toner cartridge replenishes toner to the developing unit at one time. The photo-electronic sensor detects toner in the developing unit. The CPU processes an output signal from the photo-electronic sensor to create comparison data, then compares comparison data with a predetermined threshold and issues an alarm when the comparison data exceeds the predetermined threshold. The counter counts the number of times that toner is replenished to the developing unit. The CPU changes the threshold to a level at which an alarm is hardly issued as the number of counts in the counter increases.

摘要： A method of electrically charging a material to be charged by bringing a charging member impressed with a voltage into physical contact with the material to be charged, wherein the charging member is constituted by a flexible and electrically conducting endless sheet and a rotary insulating brush which supports the endless sheet at a position where the endless sheet and the material to be charged are in contact with each other and gives a pushing force to the endless sheet, and the endless sheet is driven actively or passively together with the insulating brush at a speed substantially in synchronism with the material to be charged while applying a charging voltage to the endless sheet. This method makes it possible to uniformly and stably charge the surface of the photosensitive material even when defects such as pinholes or the like exist in the surface of the photosensitive material, without causing the life of the photosensitive material to be shortened.
